I was going to make a silly statement: surely not all of those 275,000 need to be on the network. Then I realized how silly it was. Practically all personnel, regardless of the enterprise, need network access these days.
Example: There's a housing development going up on (what was) my usual route to work. I've noticed a lot of the workers carrying around tablets or phones. The temporary utility stand on the corner has some orange cables coming to it I suspect are fiber optic carrying broadband Internet, and there's a box with a couple antennas that's probably WiFi.
We haven't run out of VPN bandwidth yet where I work, but I've copied a crap-ton of stuff to my home laptop this weekend in case it goes belly-up.

We are handling different kinds of resources: The number of simultaneous VPN connections applies even if each connection transfers a hundred bytes a minute or less - it is a function of the table size, or whatever kind of data structure the VPN software uses to manage the connections. A larger table does not in itself imply a higher bandwidth load.
It is not given that every user needs to be connected through a VPN. E.g. my company provides a lot of documentation through ordinary web pages. Lots of workers may have to look up documentation, or possibly make company database lookups for non-sensitive data, where a simple password/TFA protected login provides enough protection.
I do most of my work through a TFA remote login. Our old VPN couldn't support enough connections to send everybody home, but we had a replacement in the trial phase that was planned to last for another few weeks. They decided to accelerate the move into ordinary operation, and it seems to handle it well, and next week I will start using it. But even if it had failed, I still could do a lot of work through non-VPN channels.
For the bandwidth question: I must say that I am quite impressed by how well the backbone networks handle this! Of course response is sluggish in rush hours, but we have had no major breakdowns, and video connections are still not as jerky as in the ADSL days  . Most likely, the providers will learn a lot from this, so they can optimize routing strategies and capacities for the next similar crisis. (E.g. if you do a traceroute, you may be suprised how many hundred miles the packet travels to cross the road. A few years ago, here in Norway every packet that did not have origin and destination with the same ISP went via an Internet Exchange in Oslo, which might be a 3000 km round trip. Today, there are exchanges in a handful towns, but I guess the current experience will give valuable input to new locations where such exchanges can reduce backbone load.)

In order to telework, they all have to be able to connect, and as far as I know, it has to be over VPN. However, a certain number of people are still going in to work (essential personnel). However, that probably leaves at least half of the workforce trying to use VPN, AND THIS DOESN’t even consider the military personnel that need to use VPN.
It’s a mess...

Every now and then I get the urge to publish a book on the pearls we left behind.
Solutions to problems that we are fighting with today - but ten, twenty or fifty years ago, we did have solutions.
At the time, they may have been rejected because computing resources where not available. Today, they are, yet we haven't picked up the old solutions.
We may have settled on architectures where the old solutions do not fit in. So we can see what would be the solution, but we cannot make use of it.
Some solutions may not have been viable in its day - that's why it was left behind - and maybe not even today. Yet it might represent interesting concepts or approaches, that could be mind stimulating today, even though not necessarily realizable as code.
Often, I see that my own thoughts have spun further: This is a great basic concept, but it could have been expanded so-and-so. That certainly is no discredit to the concept - quite to the contrary, if your ideas to extend it could have made it even stronger.
Some concepts "sort of" exist, mostly in papers and articles, but are not commonly practiced in coding.
I've got a fair number of candidates of my own, but I'd like to hear which other concepts, techniques and models you think that today does not receives the merit that it deserves. What is your favorite forgotten concept, that we really should be aware of today?
If I really sit down to write this book, I probably will not see offhand what makes it valuable anno 2020, so I might need your explanations and references. We could start it here, and move it elsewhere if it grows too large.
Would you think it interesting to start this a "book" as a CP article, that we could develop stepwise together?

The concept that all data would include semantic meaning and the things you could do with it would be determined by plugins. This was the original vision of the GUI created by the folks at Xerox PARC, and is something I consider forgotten but that we should really be aware of today. Instead, we have monolithic OS's where the semantic nature of information is totally lost in bit streams and meaningless JSON packets. 
And I've already written a variety of articles here on CP to explore the concepts of true semantically aware data.

Many of the concepts in my book and articles on this site are more or less in that category. Maybe they haven't been left behind so much as they aren't widely known. If you drew up a list of topics, I'd pitch in if I thought I could contribute something useful.

Every month that has passed since a new concept was introduced halves the number of point awarded to any reference to that concept. So a year-old concept is worth 1/2^12, or quarter of a per mille, of a concept developed this month.

OK, so I understand that you think there is nothing to learn from the past. Anything that has ever been rejected, for whatever reason, under whatever assumptions and circumstances, should forever be forgotten and ignored, and noone should ever suggest that it might have some merit under the new and changed circumstances. A rejection of an idea should always be final and absolute.
Fine. I'd like you think so - that is your right. So I am certainly NOT going to bother you with any stuff about ideas that you have been decleared, for yourself, as rejected and carrying no value. Obviously, I cannot prevent you from looking up, or by accident come across, any such idea that you consider rejected and without value, but I certainly feel no need to force it onto you. You go ahead hunting the freely roaming game, whether it be the web framework of the week, the next programming language to hit the Tiobe index as the fastest growing one, or whatever. Anything else is just soooo 2019, and not worth a dime!

Yes, I thought it was a joke, too[^].
And this[^].
And at least a dozen others.
It's reminiscent of what happens if you tell your granny that the format command is used for cleaning discs.

On win10, with visual studio in order to open forms in a designer on a project you downloaded you have to unblock the corresponding resource file usually using the shell and right clicking on the file and clicking "unblock"
For a project with a lot of resources this gets really tedious.
Does anyone have a trick little utility for this? Something other than maybe powershell (i prefer not to have to fire that up)

Unblock-File[^]
Pipe your folder to the command.

I don't know if this is applicable in this case, but typically if you extract the content of a zip file that itself got the "downloaded from the internet" attribute, all extracted files will get that attribute as well.
My solution when I get this is to remove that attribute from the .zip file first (right-click in Explorer, Properties, Unblock), then extract. The attribute won't be propagated.

For the details:
The indicator telling that this file was retrieved from the Internet is represented by an alternate data stream (ADS) in the file, named Zone.Identifier. Some software saves only the "ZoneId" in this stream, others save the orgin URL as well.
In a script, you can remove all ASDs from a file using the SysInternals "streams" utility. Or you can use a recent version of PowerShell, which allows you to remove a selected ADS without affecting others.
(I provided this hint, as a solution to issues reported by our customers, to one of our developers who has been set to putting together a tool file for our Windows customers. He sneered back (in an email, so this is a direct quote): "I am fortunately not a windows developer, I hope I will never have to claim that". Maybe he is the wrong man for the job...)

Jeeze, how many times have I put off and put off looking for a method or tool for fixing some niggling problem, only to find that it's already sitting on my machine in either the SysInternals or the NirSoft directory?

I was going to bring that into the conversation but couldn't quite bring myself to writing a few paragraphs about it.
Something else that should work: Copy the downloaded file(s) to a destination that only supports FAT32 (even if just temporarily), then bring it back. Unlike NTFS, FAT32 doesn't support alternate streams, so it effectively drops the attribute.
